【摘要】 根据短肢剪力墙受力—变形—损伤—破坏特点及规律,提出了墙端有限塑性域和墙端有限损伤域的概念。建立了短肢剪力墙条在材料层次上的损伤累积模型。利用墙条纵向协调与横向组合,建立了短肢剪力墙单元分析模型,推导出了短肢剪力墙考虑损伤累积的墙元刚度矩阵,最后,通过算例说明了本文方法应用的可行性。更多还原

【Abstract】 According to the stress-deformation-damage-failure features and regular of short-leg shear wall,the hypothesis of limited damage region and finite plastic region close to two end is proposed.A model of material for the damage cumulation of the stripe of short-leg shear wall is established.Taking advantage of longitudinal coordination and crosswise corporation of stripe wall,a analysis of model of short-leg shear wall is established.And the stiffness matrix of short-leg shear wall with consideration of damage cumulation is set up.Finally,a example shows that the design method presented in this paper is feasible.更多还原
